Prevalence and you will agreement
30.4% (thirteen.6% overweight and you may sixteen.8% obesity), 32.0% off boys and you can twenty-eight.8% out of girls, had been discovered to be along side required fit weight predicated on brand new Who site (Fig. 2). At the same time, the fresh new IOTF system advertised 23.1% (fourteen.1% overweight and you may nine.0% obesity), having 22.5% in the boys and you may 23.8% inside the girls. Despite sex and classification program, obese and you can obesity try higher in metropolitan and private colleges than those regarding rural and you can public colleges (Dining tables 2 and you can 3). Concurrently, ow/ob try large certainly younger children when comparing to old of those. Differences in the newest prevalence of over weight and you may obesity amongst the Exactly who and you may IOTF system varied regarding 4.5 so you’re able to 10.9%. To have carrying excess fat alone, this type of rates varied out-of 2.dos so you can 9.3%. These variations were large during the boys than in girls.

Desk step three Prevalence away from obesity away from college or university-aged college students according to the Exactly who and you can IOTF gains records, throughout the analytical dataset, Este Salvador,
All round kappa really worth is actually 0.83[95%CI: 0.829–0.834] (good agreement) between your Which while the IOTF system (Dining table cuatro). Of the decades, kappa had a tendency to decrease in old ages, mostly just after 8 yrs old, reporting a hefty concordance.

Multilevel studies
From the arbitrary perception area, the fresh partition variance are based on the latest null InternationalWomen model (no explanatory parameters integrated) and you will adjusted designs (Dining table 5, Table 6). The latest ICC from the college student height to your Which system told me a little over ninety five.9% of your own complete variance. At school/municipal and you will municipal alone, this new ICC are eight.03 and you will 1.6%, correspondingly. Such rates on beginner, school/civil and you will civil alone level was 92.7, 5.6 and you will step 1.6% respectively into the IOTF system. Regardless of the reduced said difference at school and you may municipality, brand new multilevel model (as well as the predictors) was rather common along the solitary model (maybe not accounted for clustering study) and carry out much better than this new null model (no predictors). It means you to definitely BMIZ behaved once the centered observations, with a few level of clustering at college and you will civil height.

The fixed effects in both models showed similar conclusions. Boys, children attending urban schools, and children from private schools had higher BMIZ than girls, rural and public school children. The regression coefficients by sex were higher using the WHO system (0.14, p-value < 0.01)>
Spatial analysis
I checked out new incidence out-of ow/ob over the municipalities making use of the Who and you may IOTF expertise. The newest Moran’s List for the joint obese and you will being obese and obesity alone was in fact 0.434 and 0.359, respectively (p-really worth = 0.001) utilizing the Just who system. These rates using the IOTF system was basically 0.561 and you will 0.552 (p-really worth = 0.001). After that, your neighborhood clustering centered on Getis-Ord Gi* recognized extreme civil clusters to have heavy and obesity (Fig. 3).
